(CNN) -- Grief and sorrow know no borders, but Sunday's Ethiopian Airline crash is truly an international tragedy.

The Nairobi, Kenya-bound plane went down within minutes of taking off from Addis Ababa.

The crash killed 157 people, seven of them crew members and one a security official, an airline spokeswoman said. The passengers were from 35 nations, the airline said, with the greatest share from Kenya.

Nineteen United Nations staff members were among those killed, the UN said.

The staffers worked for the World Food Programme, the Office of the High Commissioner on Refugees, the International Telecommunications Union, the Food and Agriculture Organization, International Organization for Migration in South Sudan, World Bank and UN Assistance Mission in Somalia, and the UN Office in Nairobi.

Though it's not clear why UN employees were on the plane, the UN Environment Assembly was scheduled to begin Monday in Nairobi.

Here's what we know about the names and nationalities of the passengers and the security official. The airline has not yet reported the crew members' home countries.
